Labview not updating gui

I refuse to put it on my resume and will avoid any job that requires it. Matlab is not traditionally used to do real-time analysis. But still Matlab and Labview are both extending their capabilities toward each other market.But I feel it is a good example as you should be able to run it on your laptop. Here is the code : function real Video() % Define frame rate Number Frame Display Per Second=10; % Open figure h Figure=figure(1); % Set-up webcam video input try % For windows vid = videoinput('winvideo', 1); catch try % For macs.vid = videoinput('macvideo', 1); catch errordlg('No webcam available'); end end % Set parameters for video % Acquire only one frame each time set(vid,'Frames Per Trigger',1); % Go on forever until stopped set(vid,'Trigger Repeat', Inf); % Get a grayscale image set(vid,'Returned Color Space','grayscale'); triggerconfig(vid, 'Manual'); % set up timer object Timer Data=timer('Timer Fcn', ,'Period',1/Number Frame Display Per Second,'Execution Mode','fixed Rate','Busy Mode','drop'); % Start video and timer object start(vid); start(Timer Data); % We go on until the figure is closed uiwait(h Figure); % Clean up everything stop(Timer Data); delete(Timer Data); stop(vid); delete(vid); % clear persistent variables clear functions; % This function is called by the timer to display one frame of the figure function Frame Rate Display(obj, event,vid) persistent IM; persistent handles Raw; persistent handles Plot; trigger(vid); IM=getdata(vid,1,'uint8'); if isempty(handles Raw) % if first execution, we create the figure objects subplot(2,1,1); handles Raw=imagesc(IM); title('Current Image'); % Plot first value Values=mean(IM(:)); subplot(2,1,2); handles Plot=plot(Values); title('Average of Frame'); xlabel('Frame number'); ylabel('Average value (au)'); else % We only update what is needed set(handles Raw,'CData', IM); Value=mean(IM(:)); Old Values=get(handles Plot,'YData'); set(handles Plot,'YData',[Old Values Value]); end There are two functions. It acquires a picture every time ‘trigger(vid);’ is sent.Because my robot’s control system runs on a Lab VIEW real-time machine, I have no recourse but to add new features in Lab VIEW.Oh, I tried coding new stuff in C on another computer and streaming information via UDP over gigabit, but alas, additional latencies of just a few milliseconds are enough to make significant differences in performance when your control loop runs at 2 k Hz.

example is based on my own application to truck temperature, humidity and air pressure from different sources.

Provides simple way of creating GUI for TFT-touch and OLED displays.

Chart windows, labels, buttons, editable text boxes, tab controls help to develop complex user interface for Arduino applications more complex example where signal is measured on analog pin and plotted on chart window.

The programming paradigm used in Lab VIEW, sometimes called G, is based on data availability.

If there is enough data available to a sub VI or function, that sub VI or function will execute.

While I am sure Lab VIEW is appropriate for something, I have yet to find it. But my point is, I am now reasonably proficient in Lab VIEW basics and still have no idea how people manage to get things coded in Lab VIEW without wanting to tear their hair out.

  2. Even Gosling noted that fans were downright pissed at him when they found out they broke up in 2007. "A girl came up to me on the street and she almost smacked me. ) that the actors got along so badly on set that Gosling wanted another actress to take the place of Mc Adams to practice his scenes. He said, "The rest of the film wasn't smooth sailing, but it was smoother sailing." Like many sad endings to relationships, Gosling and Mc Adams likely broke up simply because they weren't "the one" for each other.
